Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. For ease of description, it is set in the inlet valve 12 and the outlet valve 15, the end close to the knob 14 is the outer end, and the opposite direction is the inner end.

[0015] like figure 1 , 2 , 3, the present invention includes a culture box 45 and a negative pressure compensation device. The cavity of the culture box 45 is used to place the anaerobic culture dish, and the corresponding cross-sectional area can be designed according to the demand. The lower ends of the lower ends are respectively provided with matching thread structures, and the culture box 45 and the negative pressure compensating device can be sealed and connected through the thread structures.

[0016] The negative pressure compensating device includes a cylindrical tank body 17 with an open lower end, and the tank body 17 is provided with a partition plate 10 and ...

Abstract

The invention discloses a low-pressure anaerobic bacterium culture device and belongs to the field of medical equipment. The low-pressure anaerobic bacterium culture device is characterized by comprising a culture box and a negative-pressure compensation device, wherein the negative-pressure compensation device comprises a cylindrical tank body with an opening formed in the lower end; the tank body is internally provided with a separation plate and a piston; the separation plate is fixed in the middle position of the tank body and is used for dividing the inner part of the tank body into two cavities of upper and lower parts, i.e., an upper cavity and a lower cavity; the piston is located in the upper cavity; the periphery of the piston is in airtight connection with the inner surface of the tank body; a gas inlet valve and a gas outlet valve are arranged in the lower cavity of the tank body; the gas inlet valve is communicated with the lower cavity and a gas inlet device of oxygen-free gas outside the tank body; the gas outlet valve is communicated with the lower cavity and the upper cavity. Compared with the prior art, the low-pressure anaerobic bacterium culture device has the characteristic of capability of providing a low-pressure and oxygen-free culture environment.

Description

technical field [0001] The invention relates to a medical device, in particular to a low-pressure anaerobic culture device. Background technique [0002] Anaerobic bacteria, a type of bacteria that grow better under anaerobic conditions than in aerobic environments, can be divided into obligate anaerobes, microaerophilic anaerobes and facultative anaerobes according to the degree of tolerance to oxygen. Oxygen bacteria. The culture method is to put the anaerobic medium into an anaerobic environment (select an anaerobic or hypoxic environment according to the requirements of the target bacteria), and the anaerobic environment is provided by anaerobic cylinder, anaerobic bag, anaerobic glove box, etc. . For some special bacteria, such as bacteria or other microorganisms living in high-altitude environments, a stable low-pressure environment is required to simulate cultivation. [0003] At present, only the anaerobic glove box can take into account the two conditions of low ...
